invalid_parameter being called during fread

[rdivakar]

Hi,

I have an utility service that does file copy.

In my utility I'm writing to temp file in C:\WINDOWS\Temp and later copying the content of the temp file to my actual file.

But sometime my service crashes with the below call stack. I'm not sure what is the reason.

I checked if the temp file is corrupted but i see that the temp file is valid.

Any idea what would be causing this crash?
